I have sql order by asc query and i have to order varchar field which contains integer value(I can't change the data type to int as there is already lots of data in that table changing may lose data). Result of the sorting is as following
1 2 3 . . 8 9 10 101 102 103 . . 109 11 110 111 . . 119 12

Result should be 1 2 3 . . 8 9 10 11 12

query is

C#

dbAccess.execute("SELECT [id],[SNo],LetterSNO,[SubjectOfLetter],[FrmWhere],[WhomTosend],(Cast(Day(DateOfRecieve) as Varchar(3))+'/'+Cast(Month(DateOfRecieve) as Varchar(2))+'/'+Cast(Year(DateOfRecieve) as Varchar(4))) as DateOfRecieve ,[Remarks] ,[User_IPAddress], (Cast(Day(DateOfSending) as Varchar(3))+'/'+Cast(Month(DateOfSending) as Varchar(2))+'/'+Cast(Year(DateOfSending) as Varchar(4))) as DateOfSending FROM [MpscdrcTESTING].[dbo].[tbl_PostalEntry] where DateOfRecieve between '" + TextBox1.Text.Trim() + "' and  '" + TextBox2.Text.Trim() + "' order by SNo asc";

use cast function and change the query by below.

dbAccess.execute("SELECT [id],CAST([SNo] as int) as SNumber,LetterSNO,[SubjectOfLetter],[FrmWhere],[WhomTosend],(Cast(Day(DateOfRecieve) as Varchar(3))+'/'+Cast(Month(DateOfRecieve) as Varchar(2))+'/'+Cast(Year(DateOfRecieve) as Varchar(4))) as DateOfRecieve ,[Remarks] ,[User_IPAddress], (Cast(Day(DateOfSending) as Varchar(3))+'/'+Cast(Month(DateOfSending) as Varchar(2))+'/'+Cast(Year(DateOfSending) as Varchar(4))) as DateOfSending FROM [MpscdrcTESTING].[dbo].[tbl_PostalEntry] where DateOfRecieve between '" + TextBox1.Text.Trim() + "' and  '" + TextBox2.Text.Trim() + "' order by 2 asc";
